Problems solved by technology

But on the other hand, because of its high strength and high bending resistance, honeycomb paperboard cannot be bent as easily as corrugated cardboard to form regular folding packaging cartons, but can only be used to make cushioning linings in packaging boxes. pieces or packing pallets etc.
Compared with corrugated cardboard, honeycomb cardboard is expensive, difficult to process, and poor in formability, which greatly restricts its application range as packaging materials

Embodiment 1

[0038] A diamond-shaped honeycomb paperboard and its manufacturing process. The diamond-shaped cardboard at least includes an upper surface layer, a lower surface layer and a sandwich layer, and is characterized in that the sandwich layer is a diamond-shaped honeycomb structure layer formed by splicing "V"-shaped paper strips. The processing technology of described rhombus cardboard is:

[0039] In the existing corrugated cardboard production line, V-shaped corrugated rollers are used to roll the corrugated base paper into a V shape in a similar manner to the production of corrugated medium paper, and then form a 1 to 8mm wide corrugated edge on the "V"-shaped corrugated edge. Then apply adhesive to the upper and lower peaks of the formed V-shaped core paper to obtain the first layer of V-shaped core paper with glue ribs; use the same method to obtain the second layer, the third layer, ..., the m-th layer of V-shaped core paper with glue ribs; then the m layers of core paper ...

Embodiment 2

[0041] Embodiment 2 has the same structure as Embodiment 1, except that the processing and manufacturing process of diamond-shaped cardboard is: first cut the above-mentioned paper base into core strips on the paper cutter according to the thickness of the cardboard, and then stretch the core strips to the required shape. horn. The forming angle is the two opposite angles of the rhombus quadrilateral in the stretching direction after forming; the value range of the forming angle of the rhombus grid is 30°-160°. The forming angle of the rhombus grid in this embodiment is 90°. At this time, the sandwich honeycomb is a regular quadrilateral; the characteristic of the regular quadrilateral honeycomb cardboard is that the bearing capacity of the cardboard on the four sides perpendicular to the edge is basically the same, that is, it is approximately orthotropic.

Embodiment 3

[0043] The structure of the third embodiment is the same as that of the first embodiment, except that the processing and manufacturing process of the diamond-shaped cardboard is: molding of the diamond-shaped honeycomb cushioning material. Apply adhesive on the upper and lower sides of the stretched mesh sandwich layer and paste the upper surface layer and the lower surface layer composed of facial paper to form a diamond-shaped honeycomb paperboard with a fixed size.

Abstract

The invention provides a rhombic honeycomb sandwich and a method to make the sandwich. The rhombic honeycomb sandwich at least comprises an upper surface layer, a lower surface layer and a core layer. The rhombic honeycomb sandwich is characterized in that the core layer is a rhombic grid-shaped layer in the honeycomb structure, which is formed by joining upright flaky base materials. The rhombic layer in the honeycomb structure is formed by erectly and oppositely superposing V-shaped scrip folded. Two pieces of superposed V-shaped scrip form the rhombic grid shape by oppositely superposing the tops of the two pieces of superposed V-shaped scrip. A press mark 1mm to 8mm wide is pressed on the oppositely superposed tops to ensure that the two pieces of superposed V-shaped scrip are bonded together firmly, thus forming a rhombic grid having bonding edges.

Description

technical field [0001] The invention relates to a structure and a forming method of a sandwich board, in particular to a structure and a forming method of a multilayer composite board with a diamond-shaped core. Background technique [0002] With the development of society and the advancement of technology, paper packaging containers are used in product packaging in various industries because of their advantages such as light weight, easy processing and molding, good printing suitability, recyclable reuse, and no pollution to the environment. Its application is more and more extensive. In China, the output value of paper packaging products accounts for about 40% of the output value of the packaging industry, while economically developed countries account for more than 45%. In 1871, American Albert Jones (Albert Jones) invented single-sided corrugated cardboard for packaging glass lampshades and similar fragile items, and obtained the first patent right in the United States....
